LAHORE - PIA Planetarium at Chouburji is not only the source of recreation to school and college students but also imparting knowledge of astronomy to them which is not available in the books prepared by Punjab Text Book Board or Pakistan Text Book Board, claimed a PIA officer on Monday. He said that there were errors in the books of astronomy of Punjab and Pakistan Text Book Boards but these boards were not ready to review these errors.
